frame It), as shown in'Figs, -1 to-3,-is comprised of '455p1ate r la vly. Stif amplefrictionallen a er a T-section strap ll having-a centerflange; The frame I0 is very stron and-isformed-very simply. by miteringout the center flangeatthe' points where the strap I I is bent to formthe rectangua mentJby'the' plat Zllfancl the strap's'tfwiththie pole 311is-insured to maintain; the sign .in its desired positiomon the 'pole'qjAt the same time, thepla'teQllf-being held between the straps 3 I, and

lar frame Hi, the ends of the strap l I being welded the pole-30;affdrd's' ample lateral supportfo the together by the-weldl2,*-as-"shown in Figs. 1 and 3. With the frame I!) thus formed, it willbe provided with a top flange l3, bottom flange 14, front flange l5,and. back, flange I 6. As shown most frame It to *preventits beingturned; with the back side l9 of theframe as an approximate axis, on thepole 30.

From the foregoing it is apparent that the clearly in Fig. 3, however,the back flange I6 does p ng p at 20, when Spre w l y ma ntain the illunder tension. Thus, if the straps 3! are stretched or otherwiseslightly loosened by wind loads, for example, the plate 20 will take upany slack in the straps 3| and maintain the straps 3| tight around thepole 30. The spring plate 2|] will perform its function of tensioningthe fastening strap on a pole or post of any configuration except wherethe curvature of the pole is identical with the natural set of thespringplate. This contingency may ,be

avoided, howeverfbyreveifsing thegflcurvatureof the plate shown inthedrawin'gsor by'making the plate 20 of an irregular configuration.

It is also apparent from theforegoing, thatthe frame I 0 may be mountedin a horizontal position on substantially any type of vertical post. Ifthe post is tapered, one of the fastem'ng'straps will simply betensioned less than the other; If

the post is fluted, the edges of the plate 20 will either bemechanically engaged in the flutingsplate being spaced from each otherwhen said tions of adjacent surfaces of the post and spring lfiii-springplate is unstressed, and a fastening strap or restnpon the unflutedsurface of, the post in thesame manner in which it rests face of anunfluted post.

p n the s Itis obvious that for stability preferably-two fasteningstraps, rather than one, are employed to mount the frame 10 on a post;Insofar: as the circumference of a postwill accommodate a plue.

rality of post plates and; fastening means for the 'fastening'straps,any number of signs may be fastened byone or a pair of fasteningstraps.- A preferredmanner of mounting tWo'signs-on one post, -however,isj shown in Figs. 1 and2. By;

employing a common fastening strap 3| which" passes through the upperfastening Istrapopening in one signiand the lower strap-opening in theother sign, each sign; thus may be furthersecured bya separate strapcarrying a portion of the load imposed by only one sign. "'Thisman-L'ner of securing two signs xto'one post is obviously more economical thanemploying 'a separate pair of fastening straps e ually secure Anothermodification of for a single sign plate, thatis, a sign plate car-'rying printing on both sides. As shown'in FigsJ and has been found to bemy: sign frame, as 1 shown in Figs. 4 and 5, is'particularly designed 4and 5, thefrarnedlll is'compri'sed ofa fiat strap HI bentinto arectangular form and butt welded at the baclg s'ideHQdf the' frame.spring plate is welded 'or otherwise secured to the frame H0 in thesame'manner as the spring platen" is secured to the frame ;lll. 'Lugs H5and Bare welded or otherwisesecure'dto f the j inside of the front andback sides of the frame H0. It should be noted that these lugs areoppositely offset in a clockwise direction from, the verticalcenter'plane of the frame.- Thus,

when thesign plate I22 is secured in the frame, it lies inthe verticalcenter plane of the frame and only a right-hand end ,portionof eachjfacef of the sign plate will be obscured by a lug I IE or H6.Consequently, only the least important end v of astreet' sign, forexample, will be obscured'by the fastening lug;

From the foregoing, it is apparent. that either modification of my signframe affords,a. project ing rim which protects the edges of the signplate from injury and that there are a of recesses and crevices for thecollectionflof moisturev which would promote corrosion,-
